Would it be possible that you implement some "Basic" indicators and charting (drawing) functions? Build in charting software. Like Meta Trader.
marcus03, great job! here is a very nice c++ TA lib for solaris.
it's open source and works very well. should fit fine with your code.
http://ta-lib.org/ps: some candlestick patterns needs a review (have to check with my code which ones)
but all other indicators are proved and giving correct results.
